Abstract
A packaging pouch (,) with an integral drinking straw or pouring spout (,) and an easy-to-open protective region providing access to the drinking straw or pouring spout, features a first compartment (,) to accommodate the contents e.g. a drink and—separated in a fluid-tight manner—a second compartment (,) to accommodate a tube part (,). The tube (,) leads from the first compartment (,) to the second compartment (,) and is joined in the transition region to the pouch (,) in a fluid-tight manner and features a valve element for opening and closing a through-flow channel (,). At the end projecting into the second compartment the tube features a closure (,) which is closed in a fluid-tight manner when the pouch is in the unopened state and contains a valve element (,) which, under the action of pressure from the side, frees a through-flow channel (,) and which closes automatically.
